ViewSonic X10-4K Review

September 29, 2019

A portable 4K projector that does the job.

When you first see the ViewSonic X10-4K, you wouldn’t think that it’s actually a projector. This projector moves away from the typical bulky design and actually presents itself as a portable device that you can literally bring anywhere.

The X10-4K features a stylish exterior, and its portability is made even better with a handle that folds away for easier transport. You won’t see the connectivity ports at first since they’re cleverly hidden by a magnetic cover similar to the Smart Covers on the iPad.

ViewSonic’s 4K projector is also the first device we tested that doesn’t use a traditional lamp. Instead, the X10-4K has a LED-based light engine that can output 2,400 lumens with a rated life of 30,000 hours. There’s a stand located below the unit to easily adjust the image. Combine that with the keystone and focus adjustments that automatically adjust and you’ll be using the X10-4K in minutes.

The X10-4K supports 4K and even HDR10, perfect for watching movies or even playing games. It can support 83 percent of the DCI-P3 color gamut and can project images of up to 200 inches diagonal. 

This projector is jam-packed with nifty features. One of them includes an Eye Protection motion sensor that automatically turns off the light on the projector if it senses something in front of it. The best part may probably be the built-in Harman Kardon speakers that are placed on each side of the X10-4K.

Projector speakers are usually bad, but the inclusion of the Harman Kardon speakers gave some of the best sounds we’ve heard from this type of devices. What’s more, there’s Bluetooth functionality that lets you connect any device and use it as a portable speaker. ViewSonic gets plus points just for that feature alone.

Aside from the remote, the X10-4K includes a Wi-Fi dongle that needs to be plugged in if you want to connect it wirelessly to your network. An Ethernet port is also present in case you prefer a wired connection. Joining those connections are dual HDMI ports that support HDCP 2.2 along with two USB (2.0/3.0) ports, a microSD card reader and an optical audio input.

The Android-based operating system is fast and fluid, though you don’t have access to the Play Store. Instead, there’s an Aptoide store where you can download apps like Plex and Netflix. Unfortunately, Netflix can only play content at 480p, so it’s better to just use another source (like a console) for these apps. There’s also support for Alexa and Google Assistant.

I hooked up the X10-4K to an Xbox One X so I can test its capabilities on games, physical media, and streaming. The projector offers six picture modes, but I configured one profile that would best match my personal settings. I popped in Call of Duty Black Ops 4, and while HDR looked great, there’s a bit of lag that happens when playing. Others may not notice, but serious gamers might get irked with these flaws.

On watching movies for example, the X10-4K showcased a decent color output, especially in HDR mode. That being said, the image could use a little more brightness which at times can be achieved by tweaking the settings. Dark movies looked good, though black levels sometimes tend to be a little grayish. The detail is crisp though, especially with bright scenes.

Overall, the X10-4K delivers a decent image output and excels on other features. We were also impressed by the incredible sound output of the Harman Kardon speakers, something we never experienced on other projectors.

We Love: 

+ Great design

+ Support for Alexa and Google Assistant

+ Good-sounding speakers

We Hate: 

– Mediocre HDR

Final Rating: 3.5/5
